To all whom z'tmay concern: i

Be it known that I, GiLEs VALINTINE SUL' LIVAN, a citizen of the UnitedStates, residing in the city and county of San Francisco, State ofCalifornia, have invented a new and useful Hydraulic Press for Turbine-W'heels, of which the following is aspecification. i a j In the art ofassembling turbine wheels of the type usually used for the propulsion ofmarine vessels with respect to their shafts, and wherein the latter areforcibly pressed into said wheels as by hydraulic pressure, it isessential that said shaft he forced into said turbine wheel in a uniformand expeditious manner, and it is also essentialthat the hydraulic rambe expeditiously returned to its initial or normal position']Inorderthat this operation may be facilitated andmarried on with aminimum of labor and expense, I have devised a novel construction andcollocation of a hydraulic cylinder and ram mounted on a laterallyextending upper frame work, in conjunction with a lower supporting framefor the wheel andshaft, during the operation of presslngthe latter intothe former, bothof said frames bein braced and stayed or tied togetherina nove manner, so that the upper framework properly takes up thethrust of the ram, when it is applied to the shaft which is to be forcedinto the turbine wheel. In performing operations of this character,thepressure e2;- erted is frequently very high and itises sential thatthe connections between the upper frame supporting therain and the lowerframe or bed supporting the turbine wheel and shaft, during theassembling operations, be very rigid and further thatprovision be madefor effecting a slight up and down adjustment ofthe outer ends of saidframes whendesired or necessary, so that the vertical aXial lineofmovement of the ram may always be coincident with the axial verticaldownward line ofmovement of the shaft with respect to the turbine" wheeland to provide forsuch adjustment, I employ a tie rod passing throughthe upper and lower frames and having adjustingdevices collocatedthereon above and below the outer ends of the upper and lower frames.

To the above ends,jImount said upper and lower frames upon a rigidupright and tie them together at their outer ends, by a n p fi t noIlettrs e 5 Patented line 24, 1919. 1 Application filed November 8,1918.Serial No; 261,625.

tie rod, having upper and lower adjusting devices, with respect to theouter end of each frame, provision being made for effecting theautomatic return or elevation of the ramby means of counterweightscarried by connections passing over sheaves mounted in bearingsintheupper frame work, one end ofsaid connections being secured to a yokeattached to the head of the ram, and the other ends of said connectionscarrying said counterweights. l 9

For thepurpose of illustrating my invention, have shown in theaccompanying [drawings certain forms thereof which are at presentpreferred by me, since the same will give in practice satisfactory andreli- "ableresults. It is to be understood, however, thati the variousinstrumentalities of which my invention consists can be variouslyarranged and. organized and that my -1nvent1on 1s .110t111111i3GCli30the precisearrangement andorganization of these instrumentalitiesasherein shown and described. 1 Figure 1 represents a side elevation of ahydraulic press for turbine wheels embodying my invention.

Fig. 2represents a topiplan view of Fig. 1. :Fig. 3 represents a topplan view of Fig.

1, with the sheaves and ropes removed, and

4 represents a section on line k4 Fig. 1, showing the constructionof thelower frameor bed. i i 9 In carrying out my invention I employ anangular supporting upright or standard 1, the base 2 of which may bebolted or secured to afoundation. At: the upperportion of saidupright,Isecure an upper laterally extending frame 3,comprising a plurality ofplates 3? providedat their left-hand ends "with flanges or feet 4, whichare secured by boltjsor other fastening devices 5 to the upperportion ofthe upright flange 6 of the standardl. The central portions of the up-"per laterally extending frame 8 are bulged outwardly to form *thecurved clamping members 7, which are held together by means of the bolts8, it being apparent that the tightening of saidbolts 8*clamps in positionthe hydraulic cylinder 9, within which the ram l0 is contained andreciprocates.

The outer ends of the pair of plates 3* are secured in assembledposition by'means of the outer or right-hand boltsor other fasteningdevices 12, said plates 3jbeing spaced apart by means of the distancepieces 11 surrounding the boltsS and 12, and at their outer ends theextension 1.3 of the bracket 14 may enter as seen in Fig. 2, saidbracket 7 ends of the plates 3 rest upon a washer or the flange 16 ofthe nut 17-, which is mounted or threaded upon the tie rod. 18. :whoseupper end passes between the plates 3 and is threaded for engagementwith the-upper nuts 19. The lower endof said tie rod 18 is also threadedand engages the bottom nut 19, which rests upon a foundation or base, aswill be evident from Fig. 1.

The lower laterally ext-ending frame 20, which constitutes. a'bed forsupporting the turbine wheel and its shaft, is constructed insubstantially the same way as the upper lateralframe 3, as'will beunderstood from Fig. 4E, and its outer end is supported 'between thenuts21 and 22, which are securely locked in position by the-lock nuts23.

245 designates a sheave mounted on the top of the, frame 3, inabracket'24f, and 25 and 26 designate sheaves mounted respectively inbrackets 27 and 28 secured respectively to the top of the upper frame 3and to the upper left-hand portion of the upright 1.

29 designates a yoke attached in any manner to the ram 10 and havingattached to one end thereof, a wire rope or the like 30, which passesover the sheaves 24 and 15 and carries'at its outerextremity acounterbalance 31. p

32 designates a wire rope or the like attached to the opposite end ofthe yoke 29 and passing over the sheaves 25 and 26 and carrying at itsouter end the weight or counterbalance 33. V

' 34 designates a turbine wheel shaft, and 35 designates a turbinewheel, the hub 36 of the latter-resting upon the toptof the lower frameor bed 20,which it will be understood has a central aperture 37 so as topermit the shaft 34 to enter and pass therethrough, when it is pressedinto the turbine wheel.

, The operation 'is'as follows The turbine wheel 35 having been placedin position upon the lower supporting frame or bed 20 and its shaft '34having been placed thereupon, and the requisite hydraulic or otherpressure having been created in the hydraulic cylinder 9 in the usualmanner, the

ram 10, yoke 29 andthe connections 30 and 32 move or are pressed"oryforced downwardly until the shaft 34' has been pressed into theturbine wheel 35 to the desired extent, as'will be; understood from Fig.l.

Upon releasing the pressure fromthe hydraulic cylinder 9, the weightofthe counterbalances '31 and 33 will cause the yoke'and nthe ram 10- atonce to move upwardly into fsubstant ally the position seen 'in'Fig. 1,whereupon the shaft 34fand turbine wheel by the proper man pulation ofthe nuts 17,

19 and 21, 22 and 23, upon the rod 18. The upper frame 3 takes thethrust of the rain,

when it is applied to the shaft 34, which is to be pressed into theturbine wheel 35, and the lower frame or bed 20 forms a strong andconvenient construction for the support of the turbine wheel and shaftduring the assembling operation, and any slight adjustment of the outerends of the frames 3 and 20, can be simultaneously effected by turningthe lower nut 19, as is evident.

I have deemed it unnecessary to describe in detail the operation of thehydraulic rain employed, as any conventional type thereof may be used,the fluid pressure being conducted thereto through the liquid conduit38. V

\Vhile I have devised my invention primarily for expeditiously pressingshafts into turbine wheels, it will be apparent that I may utilize theSamefor forcing mandrels, shafts and the like into and out of otherhollow objects, .as wheels, pulleys and the like, my device beingobviously adapted for a wide range of work, and being capable of beingshipped in sections or in a knockeddown condition, and being readily setup by unskilled labor.

I am aware of the patent to Austin, No. 1,196,504, but my invention isdilferentiated therefrom by the provision of the adjusting devices forthe outer ends of the frames 3 and 20, and in the construction of saidframes and the manner of mounting and collocating the latter.

It will now be apparent that I have devised a novel and useful hydraulicpress for turbine wheels, which embodies the features of advantageenumerated as desirable in the statement of the invention and the abovedescription, and while I have, in the present instance, shown anddescribed a preferred embodiment thereof which will give in practicesatisfactory and reliable results, it is to be understood that the sameis susceptible of modification in various particulars without departingfrom the spirit or scope of the claims or sacrificing any of itsadvantages.
